A 10-K is the annual report companies are required to file with the SEC. Most people open it for the financial statements — which Leonard points out is the least useful reason to open it, because you can get all the financial statements from Morningstar or a tool like TIP Finance in seconds. What he is actually hunting for are the hidden nuggets: the footnotes, the little stories, the details that talk about how the business is doing in ways the numbers do not show. That is the biggest thing he looks for. The habit predates the skill — as a finance major forced to sit through three required science classes, he used his lab printing dollars to print huge 10-Ks and read them in the back of the biology auditorium. He admits that back then he didn't really know what he was doing; everyone said you need to read 10-Ks to be a successful investor, so he read them. The understanding of what to look for came later.
Origin
Leonard was the first person in his family to attend college and picked a good finance program without scrutinizing the curriculum — which forced him through chemistry, biology, and physics. Rather than pay attention, he spent his school-issued lab printing credit on printing huge 10-Ks and read them in the back of the biology auditorium. He was caught repeatedly and lost count of how many his teachers threw away. Years later, with a real understanding of what to look for, the habit became the footnote hunt.
Core principles
- 01Commoditized information carries no edge — financial statements are one click away on Morningstar.
- 02The edge lives in what is written, not tabulated.
- 03Footnotes describe how the business is doing in ways the numbers do not show.
- 04The reading itself is the compounding asset, even before you know what you're looking for.
- 05This is the mechanism that feeds the qualitative half of your thesis.
How to run it
- 1
Understand what a 10-K is
It is the annual report companies are required to file with the SEC. It contains the financial statements plus a great deal of narrative disclosure.
- 2
Skip the part everyone else reads for
Most people open a 10-K for the financial statements. That information is valuable but not scarce — you can get all of it from Morningstar or a tool like TIP Finance.
Pro tip If a data provider can hand you the same information in one click, reading it in the filing bought you nothing.
- 3
Hunt the footnotes and narrative details
Go for the little hidden nuggets — the footnotes, the stories, the details in the report that talk about how the business is doing that the numbers don't show. This is the biggest thing Leonard looks for.
- 4
Feed the findings into the qualitative thesis
What you surface here is the raw material for assessing management, products, culture, and industry trajectory — the unquantifiable half of the investment thesis.
- 5
Read before you fully know why
Leonard read 10-Ks for years before he had a clear model of what he was looking for. The volume built the pattern recognition that later made the hunt productive.
Pro tip Do not wait to feel qualified. The understanding is downstream of the reading, not a prerequisite for it.
In the wild
As a finance and accounting major forced through three required science classes, Leonard used the printing dollars the school gave students for the lab to print huge 10-Ks. He sat in the back of the big biology auditorium reading them instead of the lecture. He was caught several times — sometimes he'd be so absorbed he couldn't put it away when the teacher came by — and lost count of how many were thrown away.
→ He was studying what he was passionate about and what he believed would help his future. He admits he didn't really know what he was looking for then; a decade later he has a specific understanding of what to hunt for in a 10-K.
Common mistakes
Reading a 10-K for the financial statements
It is the most common reason people open the filing and the one with the least edge. The statements are available faster and cleaner from Morningstar or any finance data tool — reading them in the source document costs time and yields nothing others don't have.
Waiting until you know what you're looking for
Leonard read 10-Ks for years without a clear framework, simply because everyone said successful investors read them. The competence emerged from the repetition. Waiting for clarity first means never starting.
Is it for you?
Best for
Individual stock pickers doing genuine fundamental research who want to find what data screens and aggregators structurally cannot surface.
Not ideal for
Index investors, anyone unwilling to read long filings, or investors who need conclusions faster than deep reading allows.
From the transcript
“i'd use all those dollars to print these huge 10ks and i'd just sit in the back of the biology class in you know this…”
“back then i didn't really know what i was doing i was just getting started i really just everybody said you need to read 10ks…”
“the things that i'm looking for the most is kind of the little hidden nuggets of information that you can't get from just financial statements…”
“what i'm really looking for is the footnotes or these little stories or details in this report that talk about how the business is doing…”
